Sunfire L4-2.2L VIN 4 (1996)
Passlock Relearn Procedure
The PASSLOCK System is designed to prevent theft even if various theft deterrent parts are changed. Parts that can no longer be changed without the
possibility of going into a tamper mode are:
-
PASSLOCK Lock Cylinder
-
Instrument Panel Cluster (IPC)
-
Powertrain Control Module (PCM)
If any of these parts are replaced, the vehicle may start and stall for 10 (ten) minutes (LONG TAMPER MODE). If this occurs, the system MUST go
through a LONG TAMPER MODE cycle. During this time, the THEFT TELLTALE will be flashing for the full ten minutes. The IPC and PCM
require the full ten minutes to complete a learn cycle. The Ignition Key MUST remain in the "RUN" position until the telltale stops flashing or the
cycle will have to be repeated.
